The Marineford War is about to begin, and countless Marines have gathered at Marineford, preparing for a decisive battle against the Whitebeard Pirates! But just then, Luffy, Jinbe, and Ivankov, who were causing chaos in Impel Down, suddenly stopped. They had come across a colossal object placed at the entrance to the sixth level—a massive block of ice filled with seawater! And inside this ice block, a figure seemed to be floating! Who is this woman sealed inside?!

Jinbe the Sea Knight: I have heard that twenty years ago there was a Marine Admiral who, in a fit of rage, turned the first half of the Grand Line into a sea of ​​blood!

The Warring States of Buddha: In order to win this war, it seems we must release her from the "Sea Tower Ice Prison"!

Hero Garp: If she awakens, this war will be thrown into complete chaos!

Akainu: Sensei, are you finally waking up?!

Whitebeard: Oh dear, you Marines actually dared to release that demon! What a mess!

Kaido: You've finally appeared! I've been waiting for you for twenty years! Let's have a good fight!

Lu Ze, 24 years old, a straight-through bachelor’s and master’s graduate from Peking University, thought he’d become an excellent teacher after graduation.

But…

“Lu Ze, tomorrow you’ll go to No. 3 High School’s Rocket Class as a temporary homeroom teacher. Remember, you’re going undercover. Your mission is to mislead those students.”

To carry out the mission, Lu Ze is forced to make a series of morally questionable moves:

“Our class gets a full weekend off. No morning or evening self-study.”

“Phones are allowed.”

“No dating in front of me.”

“Teachers aren’t allowed to assign any homework.”

“…”

Everything he’s doing is being livestreamed 24/7 on a reality show called Model Teachers.

The show also features rocket classes from two other high schools:

A strict 1980s-born homeroom teacher who enforces discipline with military-like precision.

A 1990s-born homeroom teacher who relies on emotional coaching and daily motivational speeches.

And then there’s Lu Ze, born in the 2000s—who lives by one motto: “Enjoy life while you can.”

At first, no one had any faith in Lu Ze’s class. But…

Two months later…

“Lu Ze, what the h*ll happened? Why did your class do so well on the midterms?”

Lu Ze: “Maybe their foundation was too good. Just wait—by finals, their scores will definitely drop!”

End of the semester…

“Lu Ze, what’s going on?”

Lu Ze: “Hang in there—next semester, their scores will fall for sure.”

One year later…

“LU ZE!!”

Lu Ze: “Don’t worry…”

Many years later…

“You were supposed to go undercover at No. 3 High School—how did you end up as principal?!”
